“…There is increased demand for this plant for medicinal purposes due to its astringent and urinary antiseptic properties. The plant has triterpenoids and steroids in the fruits (Grishkovets et al 1979), arbutin and (-)-epicatechin in the leaves, and monotropein, stilbericoside, unedoside, and (? )-catechin in the leaves and bark (Sakar et al 1991).…”

A protocol for micropropagation of Arbutus andrachne from seeds was developed. Results indicated that none of the seeds cultured on Murashige and Skoog (MS) medium, with or without plant growth regulators (PGRs), germinated. Seeds soaked in 250 mg l -1 gibberellic acid (GA 3 ) at 4°C for 3 days, then cultured on water-agar medium containing 2.0 mg l -1 GA 3 exhibited 80-100% germination and developed into usable seedlings. Shoot proliferation was tested on MS or B5 medium containing different concentrations of cytokinin. No shoot proliferation was observed on PGR-free medium. Proliferation was more successful on MS than on B5 medium. On both media, the most successful proliferation was obtained using zeatin as a cytokinin type. Rooting was tested on MS medium containing different concentrations of auxin. Rooting failed on PGR-free medium and on medium containing indole-3-acetic acid (IAA), 0.25 or 0.5 mg l -1 indole-3-butyric acid (IBA), or 0.25, 0.5 or 2.0 mg l -1 a-naphthaleneacetic acid (NAA). Rooting (40%) was most successful with 1.0 mg l -1 NAA. Rooted plantlets exhibited 80% survival in all mixtures of peatmoss and perlite, and acclimatized plants were successfully grown in the greenhouse. Quantitative analysis of arbutin performed on in vivo and in vitro leaves using high-performance liquid chromatography (HPLC) revealed that in vivo leaves contained higher arbutin content (0.3-0.81% w/w) than in vitro leaves (0.09% w/w). The highest yield of arbutin in vivo was detected in leaves collected in August, and the lowest yield in leaves collected in December.

“…The leaves contain arbutin, monotropein, stilbericoside, unedoside, catechin and epicatechin, while the bark contains monotropein, stilbericoside, unedoside and catechin (Sakar et al, 1991). The fruits contain triterpenoids and steroids (Grishkovets et al, 1980). The plant has narcotic constituents and tannin (Karim & Quraan, 1998).…”

The effect of the alcoholic extract of Arbutus andrachne on certain biochemical parameters and the histology of the visceral organs in nonpregnant adult female rats was studied. The lethal dose 50% (LD) 50 was estimated, and three different doses (1/10th , 1/15th and 1/20th ) of the LD 50 extracts were injected intra-peritoneally for 14 consecutive days into three groups of animals (n ¼ 5 in each group), with one group used as a control and injected with distilled water through the same route. Blood was collected after sacrificing the animals and the following biochemical parameters were detected: glutamate pyruvate transaminase (GPT), glutamate oxaloacetate transaminase, alkaline phosphatase, cholesterol, glucose, triglycerides, creatinine and bilirubin. In addition, the total white blood (WBC) and red blood cells (RBC) were estimated in the blood of all groups. The gross and microscopic findings were reported after the collection of specimens from the animals, and processed routinely for standard histological procedures. The results showed an increase in the number of WBC, which indicated a defence response; while the RBC were decreased because of damage in tissues or organs. The gross and the microscopic changes seemed to be dosedependent, as very little or no effects were noticed in the lowest treated group, and more obvious changes were detected in the highest-dose group of animals. In addition, changes were observed in almost all biochemical parameters under investigation, with the exception of creatinine and GPT, which reflect the general effect of the material used on the animal health.
